OF NEWTON, MASSACHUSETTS- METHOD OF ATTACHING HEELS TO BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 376,049, dated January3, 1888.

' Application filed April 1i), i887. Serial No. 235,318. (No model.)

To all whom it may concern( Be it known that I, CHESTER O. SMALL, ofMalden, in the county of Middlesex and State ofMassachusettaa citizen oftheUnited States, have invented a new and useful'Process of AttachingHeels to the Soles of Boots or Shoes,

of which the following is a full, clear, and exvthe boot or shoe.

act description, reference being had to the accompanying drawings,forming a part of this specification, inexplaining its nature.V

The inventionY relates to the process or method of attaching heels tothe soles of boots or shoes, comprising the compressing of theheel-blank with such pressure as may be required between two surfaces,oneof which is perforated, then puncturing or forming holes in theheel-blank with a gang or group of implements moved through said holesinto the heel-blank, then feeding or 'supplying said holes withnails,then driving said nails through the heel-blank into the sole ofthe boot or shoe by the same implements used in forming the perforationsorholves in the heel blank.

In thedrawings, FigureA 1 is a view in section, enlarged, representingthe perforate and imperforate pressure-blocks and the section of thesole of a boot or shoe and a heel-blank between them, representing theposition of. the

Vparts before the heel-blank has been compressed. Figs. 2, 3, 4, and areviews similar to Fig. 1, but showing the parts in diii'erent positionsto illustrate the successive steps of my method. Fig. 2 represents thepuncturing devices in the 'act of forming the holes. Fig. 3 shows thepuncturing devices withdrawn from the holes. Fig. 4 shows the nailsinserted in the holes preparatory to driving, and Fig. 5 represents thepuncturing devices in the act of driving the nails into the soles ofFig. 6 represents in vertical section a'portion of an apparatus for caryrying my invention into effect.

A represents one presser-block for subjecting the heel-blank to pressureupon the outsole of the boot or shoe. B represents the perforatedpressure-block. These two blocks are moved relatively to each other toco'xnpress the heel-blank with any desired degree of compression, eitherby hand or automatically.v 'lhe pressure-block B has the holes b.

D represents the gang or group of implements used. They are supported bya block, d. They are rst driven or moved forcibly through the holes b topuncture holes c in the heel-blank, and are then withdrawn to permitnails to be fed through said holes to the holes c. They are then againmoved into said holes Y to drive the nails through the heel-blank intothe sole. This movement may be by hand or it may be by power.

The nails may be fed byhand or automatically.

It will be seen that as the same gang of implements forms the holes forthe nails and drives them they are first moved through o;

the holes b sufficiently far to prick the holes, and are withdrawntherefromto permit the feeding of the nails, and are then again insertedin said holes, but are not then moved beyond the surface of the block.The'block 7o A may be perforated in addition to or instead of the blockB and a gang of implements used in connection with it to form a holethrough the soles into the heel and to drive the nails.

This process may also be used for loading detached blanks with nails andfor driving nails into` soles or other material adapted to be heldbetween two holding or pressure blocks of the character described.

The device for moving the pressure-block A 8o in relation to thepressure-block B to compress the heel-blank to any desired extent uponthe soles'of the boot or shoe comprises a cam, E, upon the verticalshaft e,rotated in any desired way. This cam has a cam-groove, e', 8 5

which receives a cam-pin upon the lever e2. This lever is pivoted at e3and operates the toggle e4, which is connected wit-h the slideblock e5,which in turn operates upon a slidepost, es, carried by the jack e7, andwhich re- 9o ceives at its upper end the block A.

In operation the boot or shoe is placed upon the presser-block A and aheel-blank placed between the outsole and the presser-block B,

and it is then compressed to any required extent between the twosupports, preferably by means of the support A and the block B. Theimplements D are then inserted in the holes b and moved through the samesufficiently far to form the holes c in the `heel-blank. (See roo Fig.2.) They are then Withdrawn and the nails are fed through the holes inthe p ressureblock to the holes c. The sanieimplements are againinserted in the holes I) and the nails 5 driven through the heel-blankand soles of the boot or shoe. In case the heel-blank is to be loadedonly, the shoe is not placed upon the support A and the implements arenot caused to drive the nails entirely through the heelro blank.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- The method of driving nails inheels, 8:0., comprising the formationin the heel of a gang 15 or groupof holes; second, in supplying said holes with nails, and, third, indriving said nails into said heel by the same implements used in formingthe holes, substantially as deseribed.
